IMPROVEMENT IN AXLE-BOXES FOR CARRIAGES.

Specification forming part of Letters Patent No. 133,494, dated November 26, 1872.

To all whom it may concern:

Be it known that I, PAUL R. STAGE, of Greensburg, in the county of Decatur and in the State ot' Indiana, have invented certain new and useful Im provement-s in Axle-Boxes; and do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawing and to the letters ot' reference marked thereon making a part of this specification.

The nature of my invention consists in the construction and arrangement of an axle-box and shoulder-band to be used on wooden axles, 'as will be hereinafter more fully set forth.

In order to enable others skilled in the art to which my invention appertains to make and use the same, I will now proceed to describe its construction and operation, referring to the annexed drawing, in whichvFigure l is a longitudinal section of my axle-box and shoulder-band.l and Fig. 2 is a cross-section taken through line w w, Fig. 1.

A represents a Wooden axle to be used Without a thimble, and having the shoulder a at the inner end of the arm or spindle of the axle. B represents a metallic band provided with an interior shoulder, b, corresponding with the shoulder a on the axle. This band is placed on the axle, as shown, strengthening the same at the inner side ofthe Wheel. C

represents the box placed in the hub of the Wheel and made to tit the arm or spindle of the axle. Around the interior of the box O is formed a recess or oil-chamber, d, which is tapering from the center of the box to either end, so that the-oil will run from the center to the ends. The recess is deep enough to hold the oil when standing, and when the wheel commences to revolve the oil begins to oil the arm.

Having thus fully described my invention,

what I claim as new, and desire to secure by Letters Patent, is-

1. An axle-box provided with an interior circumferential recess or oil-chamber tapering or increasing in depth from the center toward the ends, substantially as and for the purposes herein set forth.

2. The box B provided with the shoulde b, in combination with the Wood axle A provided with the shoulder a and the sleeve C,
